Warren, Chisora End Association

The former world title challenger and British, Commonwealth and European heavyweight champion will no longer work with, or be promoted by, Queensberry Promotions or its head honcho Frank Warren.

Chisora has fought only twice since his retirement defeat at the hands of future world title challenger Tyson Fury last November, but it has been revealed in a statement that Warren –– who engineered his WBC world title challenge against Vitali Klitschko in 2012 –– has ended his association with the 31-year-old.
